3 Claims. 1

This invention appertains to novel devices for preventing skidding in inclement weather.

An object of thisinvention is .to-provide an improved means for controlling the admission of a predetermined quantity of abrasive material in relation to the admission of a predetermined quantity of exhaust gas orgases.

Another object of this invention is to provide an improved exhaust pressure responsive valve means, adjustable in nature, for preventing the inadvertent loss of adjuvant or abrasive material.

A further object of this invention is .to provide means for resiliently biasing said "last mentioned valve means.

A still further object of this invention is topro- 'vide means for selectively adjusting said resiliently biasing means.

Another object of this invention is to provide common control means for actuating certain selective valves at predetermined intervals and at the prerogative of a vehicle operator.

Another object of the present invention is to provide resilient return means for each of said valve means actuated by said common control means.

Figure 8 is an enlarged detail of construction "taken substantially on the line 88 of Figure 1 and in the direction of the arrows.

Referring now "in -detail 'to the illustrated preferred embodiment of the present invention, like reference characters are used throughout to indicate similar elements.

This invention has been developed to provide .a device .for impeding. if not preventing, danger skidding and turning in inclement weather. Further, this invention might be utilized for the purpose of removing vehicles from stuck .orotherwise immovable positions through the medium of spraying a predetermined .quantity of abrasive material adjacent thelback Wheels thereof. .It is contemplated by the present invention .to not only eject abrasive material adjacent the rear wheels of a vehicle butalso control the said ejection in accordance with the pressure of the exhaust common to all internal combustion engine operated vehicles. It is also within the purview of the present invention to regulate the -.quantlty of exhaust and also to regulate the pressure of exhaust utilized in ejecting the .said abrasive material. For this purpose, a common control means has been provided for regulating (opening and closing) certain predetermined valves utilized in the system.

A vehicle chassis of a conventional nature is disclosed in Figure 1 and designated generally .by the reference numeral 10. The usual inter- .nal combustion engine is provided thereon having the conventional exhaust pipe 12 extending therefrom.

A conduit Ill is angularly communicating with .said exhaust pipe and a branch conduit l8 ex- .tends fromsaid above mentioned conduit. A butlterfiy valve [.8 is provided in :said exhaust pipe 12 .for the purpose .of selectively opening. and closing either the exhaust pipe or conduit 14. The construction of the said butter-fly valve .is conventional .being :a disc .20 pivoted to suitable perches 22 withinsaid-conduit and exhaust pipe. .An .arm .24 is secured .to the pivot pin and is at substantially.rightangles to the longitudinal axis thereof. A resilient biasing means, preferably a spring 25 secured .tothe said arm .24 .by anysuitable conventional means and also secured to a selected member of the chassis l0.

At the end portion of thesaid conduit i l-and .branch conduit 1.6, there is a sleeve 28 provided .therearound. The said sleeve 28 terminatesin a nozzle 30 .for ejection purposes adjacent the rear wheels of .a usual or conventional vehicle. The o posite end of the .said sleeve 28 has .a collar .32 thereunderabutting-in securing relation, the said branch conduit 15. It will .be'noted from an inspection of Figure 1 that two identical .oon- ,structions are provided in conjunction with the sleeve-ejection :means described herein now and accordingly, it is .deemed that onlyone description thereof sis-necessary. It is seen from an inspection of Figuredthat .a plurality of apertures -34 are provided the terminal portion of the said conduit 16 for mufiling purposes and also for ejecting exhaust gases radially of the conduit in order to obviate a great portion of the undesirable back pressure sometimes encountered in devices of this nature.

A bracket 3 B is secured to a convenient portion of the said chassis l and secured to a suitable perch 38 provided on a collar 40 encompassing the sleeve 28.

Going now to Figure 3, there is disclosed a hearing block 42 rigidly secured to the said sleeve 28 and a rod 44 slidably received therein. A disc valve 66 is journaled in said. sleeve 28. Suitable conventional pivot means are provided for this purpose such as the pin 48 disclosed in Figure 6. A stop 59 is provided on the interior surface of the said sleeve 28 extending substantially all the way therearound. An arm 52 is rigidly secured to the said valve plate 46 and extends through a suitable aperture 54 in said sleeve 28. A stop 55 is secured to the said arm 52 engaging the inner surface of the said sleeve forming a stop in adjusting the nut 60 and to prevent accidental opening of the valve disc 46 due to jarring during normal operation of the vehicle. An aperture 58 is received in the said arm 52 adjacent one end thereof for the purpose of receiving a portion of the rod id therethrough. An adjustable friction means, preferably a nut 69 is threadedly received on the said rod 44 thereby providing a stop means for said arm 52. A second nut 52 is also received on the said rod M for the purpose of adjustably receiving a resilient biasing spring means 64 between the bearing block 42 and the last mentioned nut '52. It is quite apparent from an inspection of Figure 3 that this construction permits of selective adjustment of a Valve means,

the said valve means being responsive to the exconducting and controlling the flow of abrasive material to the said sleeve 28. Accordingly it is believed that a description of only one of said systems is necessary for the full understanding of both thereof. A hopper or receptacle 1B is suitably secured to a convenient component of the chassis of a vehicle and a pipe '72 extends from the bottom portion thereof. The said pipe 12 extends into the said sleeve 28 thereby communicating the abrasive material carried by the said hopper with the said sleeve 23.

Valve means are provided in the said conduits '12 for the purpose of regulating the flow of abrasive material. The preferable construction of the last mentioned valve means may be seen particularly Well in Figure 8. A receptacle 14 is interposed in the line or pipe 12 and a conventional fiat valve is journaled therein. The conventional valve consists of a plate pivotally journaled on a stub shaft 18, said stub shaft extending through the said receptacle M. An arm 89 is rigidly secured to the said stub shaft extending in right angular relation thereto. Resilient means for biasing the said plate 16 in a closed position are provided in the form of a spring 82 extending between the said arm 88 and asuitable portion of the chassis in.

Taking now Figure 1, it may be readily seen that a master cable 84 is journaled about suitable pulleys 86 and 88 respectively, then said master cable 84 branches into minor cables 99 and 92 respectively. The said cable 90 extends directly to the arm 24 for the purpose of regulating the exhaust admission valve. The minor cable 92 extends rearwardly of the vehicle branching again into two portions, one of which extends to each of said arms for the purpose of regulating the abrasive material admission valve. It may be seen clearly that the amount of abrasive material may be regulated as well as the pressure from the exhaust pipe by a single actuating means. Further, the quantity of abrasive material or value of pressure taken from the exhaust line may be changed relative to each other by simple manipulation of cable, shortening or lengthening the same.

There has been described and illustrated a single preferred embodiment of the present invention capable of performing all of the specifically mentioned objects as well as ancillary objects. However, it is apparent to those skilled in the art that various changes including omissions and additions may be made herein without departing from the spirit Of the invention. Accordingly, limitation is sought only in accordance with the scope of the following claims.

Having thus described the present invention, what is claimed as novel and improved is as follows:

1. An anti-skid device comprising a vehicle chassis, an exhaust pipe secured thereto, a conduit secured to said exhaust pipe, a branch conduit communicating with said conduit, means for retaining abrasive material communicating with said conduits, valve means associated with said retaining means and said conduit, common means for actuating all of said valve means, means for resiliently urging said valve means in a closed position, a mufiler sleeve mounted at the ends of said conduit and branch conduit, pressure responsive valves disposed in said muffler sleeves, said common means comprising a plurality of cables journaled on said chassis, said cables terminating in a single master draw cable.

2. In an anti-skid device, a vehicle having a chassis and an exhaust pipe, a conduit secured to said exhaust pipe, at second conduit secured to said conduit, abrasive material retaining means on said chassis, conducting means connecting said retaining means and said conduits, valves in said conducting means and a valve at the junction of said first conduit and exhaust pipe, common means for actuating all of said valves simultaneously, a muffler sleeve at the end of said conduit and second conduit, a bearing on said sleeve, a valve in said sleeve, a rod journaled in said bearing and means for adjustably connecting said last mentioned valve and said rod.

3. The combination of claim 2, said adjustable connecting means including friction receiving means slidably received on said rod, a link connecting said last mentioned valve and said rod and a spring interposed between said friction securing means and said bearing.
